Vstupn\u00ed dom\u00e9na je term\u00edn pou\u017e\u00edvan\u00fd v softwarov\u00e9 in\u017een\u00fdrstv\u00ed<\/a> v informatice, kter\u00fd ozna\u010duje mno\u017einu v\u0161ech mo\u017en\u00fdch platn\u00fdch vstupn\u00edch hodnot, kter\u00e9 m\u016f\u017ee program nebo syst\u00e9m p\u0159ijmout.

Vstupn\u00ed dom\u00e9nu lze definovat r\u016fzn\u00fdmi zp\u016fsoby v z\u00e1vislosti na typu vyv\u00edjen\u00e9ho syst\u00e9mu nebo programu.
